Patented Dec. T2, 1916.

Application filed May 15, 1915. Serial No.28fl20.

To all whom it may concern:

Be it known that 1, WILLIAM E. MEAD- WELL, a citizen of the UnitedStates, residing at Ithaca, in the county of Tompkins and State of NewYork, have inventedi'certain new and useful Improvements inflPen andPencil Caps; and I do herebydeclare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the artto which it appertains to make and use the same.

This invention relates to new and useful improvements in pen and pencilcaps and is designed primarily to house the blade -of a steel eraser, sothat the same will be andy and may be easily and quickly put in Service.

Another object of the invention is to provide a device which may beconstructed of rubber or a similar material and in which a plunger isprovided carrying a steel blade or such a steel eraser as wouldordinarily be used on a desk or in other places where such articles arefrequently necessary.

With these and other objects in vieWE, the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawing, in which,

Figure 1 is a fragmentary view of a pen and pencil cap constructed inaccordance- With this invention showing the eraser in position to beused and showing the device applied to a pencil. Fig. 2 is a verticalsectional view showing the cap applied to a pen and the eraser Withdrawnfrom its opera- "tive position, and Fig. 3 is a top plan view of Fig. 1.

Referring to the drawings, the numeral 1 designates as an entirety theouter casing of the device comprising the tubular body 2 which is formedwith the end closure 3. This end closure is provided with a transverselyextending slot 4 through which the blade passes when the device is inuse. Formed in the side of the tubular housing 2 is a verticallyextending slot 5 provided at each end with the transverse slot 6 whichform branches and provide notches to lock the blade in its outer andinnermost position.

Slidable in the tubular body 2 is the plunger designated generally b thenumeral 7 which comprises the tubu ar body 8 provided with the endclosure 9 having formed therein a central screw threaded aperture 10 forthe reception of the threaded shank of the blade whichwill be more fullyhereinafter described. A suitable pin 11 projects laterally from thebody 8 and into the slot 5 and this pin is arranged for engagement withthe end walls of the slot and the side walls of the transverse slot 6-inholding the plade in its innermost and outermost posi- The bladehereinbefore referred to is designated generally by the numeral 12 andcomprises the body 13 having the cutting edges 14. formed thereon. Athreaded shank 15 is formed on the body and is arranged to be threadedinto the opening 10 of the plunger 7 and it will thus be seen that theblade will be rigidly held with relation to the plunger.

It will be apparent from the foregoing that when the device is not inuse the blade is normally retained within the housing 2 by turning thesame slightly so that the pin 11 will slide vertically through the slot5 and may be locked in the lower slot 6. When in this position it willbe clearly seen that the blade will be drawn into the housing and noportion thereof will project therefrom. Tn event that it is desired touse the knife or eraser, the pin 11 is movedso that it alines with theslot 5 and upon moving the same upwardly, it will be apparent that theblade will aline with. the slot 4 in the closure 3 and will passtherethrough until the upward limit of movement is reached wherein thepin is moved so as to engage the end wall of the upper slot 6 and it wll be evident that the eraser will be ready for use. 7 While in theforegoing there has been shown and described the preferred embodiment ofthis invention, it is to be understood that such changes may be made inthe combination and arrangement of parts as will fall within the spiritand scope of the appended claim.

What is claimed is A device of the class described comprising an .outercasing having a tubular body closed at one end, said closed end providedwith a transversely extending slot, said side wall of the outer casinghaving a vertical slot therein provided at each of its ends with atransverse slot, a tubular body 'of less diameter than the first namedtubular body slidably mounted therein, said second tubular body havingone end closed and having a central screw threaded aperture, a bladeprovided with a screw threaded shank removably fitted in the screwthreaded opening of the second tubular body, said second tubular bodyhaving a lug adapted to move in the vertical slot and be turned into thetransverse slots at the opposite ends of the vertical slot for holdingthe blade into and out beyond the first named tubular body, said bladewhen on the exterior of the first named tubular body and the lug isturned into the upper transverse slot, the blade will U and any rotaryor accidental inward move- 15 ment of the saine'eliminated.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM E. MEADWELL.
